SOLE AND HEEL BURNISHING MACHINE.

SPECIFICATION forming part of Letter s Patent No. 292,083, dated January 15, 1884. Application filed August 21, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that we. ALBION L. F. MIrcrI- ELL, of Lawrence, county of Essex, and State an improved machine forburnishing or setting the edges of boot and shoe soles and heels; and it consists in certain details of construction, which we will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of a machine embodying our improvement. Figs. 2 and 8 represent sec tional views of the burnishing-tools shown in Fig. 1. Fig. 4 represents an end elevation of the machine.

The same letters of reference indicate the Same parts in all the figures.

In the drawings, a represents a supportingstandard having bearings in which is journalcd a horizontal arbor, b, driven by a belt,

' 0, running from a driving-shaft, d.

e f represent burnishingtools affixed to the opposite ends of said arbor. The tool 6 has its periphery curved in cross-section, so as to approximately fit the vertical curvature of a hee1,while the tool f has a series. of peripheral divisions or surfaces, 2 3 4 5, which adapt it to different parts of the edge of the heel or sole. Each tool is made with an interior chamber, g, and a central opening, h, communicat ing with said chamber, said opening being in line with the axis of the tool. \Vithin the chamber 9 of each tool is a burner, 43, for gas or other suitable fuel, supported by an arm or bracket, j, passing through the opening It. The burner 13 is adapted to direct its flame against the portion of the wall of the chamber 9 which forms the inner surface of the burnishing portion of the tool. The tool is thus heated, and there is no deposit of products of combustion on the burnishingsurface, as there would be if the flame were applied directly to said surface. The bracket j is preferably secured to a fiXed arm, Z, by a thumbscrew, m. By loosening said screw the bracket may be loosened and adjusted so as to vary the position of the burner, and locate it nearer to or farther from the surface of the tool against which the flame is directed, thus enabling the heat of the tool to be regulated.

Although we have shown but one burner, and that applied to the tool 6, it will be understood that the tool f is to have a similar burner. l

The periphery of the tool 6 is preferably corrugated or fluted to increase its burnishing effect.

The surfaces 2 3 4 of the tool f may be formed to fit any desired part of the sole or heel edge, as before stated. The surface 5, which is abruptly beveled, is provided with radial ribs or corrugations, and is adapted to burnish the tread-surface of the top lift.

o do not limit ourselves to the employment of any particular fuel; but we prefer gas as the most convenient. VVehave found that the rapid rotation of the tool causes the air to rush in and intensify the flame nearly as effectually as when a blower is employed for the same purpose.

WVe claim- 1. The combination, in an organized burnishingmachine, of the rotating hollow burnisher open at the front, and a swinging gas burner mounted on a bracket, as described, so as to swing into the open end of the burnisher, substantially as and for the purposes set forth.

2. In an organized burnishing-machine, and in combination with a rotary shaft therein, driven by suitable mechanism, substantially as described, the burnisher described, having plane beveled surface 5, provided with radial ribs or corrugations, and adapted to burnish the tread of the heel, and having the molded surfaces 2 4, adapted to fit the 00111 our and burnish the edge of the sole or heel, substantially as described.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 15th day of August, 1883.
